dryriver writes in with a story lamenting the lack of accurate science in movies. "The relationship between science and science fiction has always been tempestuous. Gravity focuses on two astronauts stranded in space after the destruction of their space shuttle. Since Gravity's US release (it comes to the UK in November) many critics have praised the film for its scientific accuracy. But noted astrophysicist Dr Neil deGrasse Tyson, director of the Hayden Planetarium at the American Museum of Natural History in New York, had several issues with the accuracy of Gravity's portrayal of space. Through a series of posts on Twitter, Tyson — who later emphasized that he 'enjoyed the film very much' — highlighted various errors. He noted the Hubble space telescope (orbiting at 350 miles above sea level), the International Space Station (at 250 miles), and a Chinese space station could never be in line of sight of one another. On top of that, most satellites orbit west to east, yet in the film the satellite debris was seen drifting east to west. Tyson also noted how Sandra Bullock's hair did not float freely as it would in zero-gravity. This is arguably not so much an error in physics, but a reflection of the limitations of cinematic technology to accurately portray actors in zero-gravity. That is, of course, without sending them into space for the duration of the film. The Michael Bay film Armageddon is known for its woeful number of inaccuracies, from the space shuttles separating their rocket boosters and fuel tanks in close proximity to each other (risking a collision) and to objects falling on to the asteroid under a gravitational pull seemingly as strong as the Earth's. More than one interested observer tried to work out how big the bomb would have to be to blow up an asteroid in the way demanded in the movie. Answer: Very big indeed. Nasa is reported to have even used Armageddon as part of a test within their training program, asking candidates to identify all the scientific impossibilities within the film."

Nerval's Lobster writes "The upcoming movie Gravity features a pair of astronauts (George Clooney and Sandra Bullock) stranded in orbit after their space shuttle is destroyed by floating debris. Faced with dwindling oxygen levels, they struggle to reach the nearby International Space Station (ISS). It's a movie, so some deviations from reality are expected, but it also opens up an opportunity to talk with a NASA astronaut about what it's like to live in space. Catherine 'Cady' Coleman, who has spent thousands of hours aboard the Space Shuttle Columbia and the International Space Station, who gave Bullock advice on the role, suggests that the real NASA has the whole orbital-debris issue well in hand, but that it takes a lot of training (and on-the-job experience) to get the hang of living in space. 'When we get up to space and the people up there run around and show us stuff — that's really, really effective and there was nothing like that compared to the classroom.' Despite the physical and mental demands, and the the time spent away from family, she sees the endeavor as supremely worth it. 'We're all very privileged to do this job,' Coleman says. 'They spend a lot of money making you ready, and you have a responsibility to do your job.'"

Nerval's Lobster writes "The U.S. Navy expects to save $20 million per year on its global logistics and transportation budget, thanks to technology that has been saving business travelers billions since 1996. The Navy is testing a system that consolidates information about freight and personnel travel schedules into a single database—the better to give individual decision-makers a choice of the quickest, cheapest options available using 'an Expedia-like' search capability, according to the Office of Naval Research, which developed the application. All that being said, the Transportation Exploitation Tool (TET) is a little more sophisticated than online-travel sites such as Expedia or Travelocity were in 1996: The system consolidates travel schedules and capacity reports for both military and civilian carriers to give logistics planners a choice of open spaces in ships, planes, trucks, trains or other means of travel, along with information about cost, estimated time of arrival and recommendations of the most efficient route. Previously, logistics planners trying to get an engine part to a Navy ship stranded in a foreign port, for example, might spend hours or days looking through separate databases to find a ship or plane able to carry the part that could deliver it within a limited window of time. 'This system is truly revolutionary,' Bob Smith, program manager at the Office of Naval Research (ONR), wrote in a statement announcing the system. 'TET uses advances in technology to provide outstanding optimization of available flights and ship routes, saving our logisticians enormous amounts of time—and that can literally mean saving lives.'"

Hugh Pickens DOT Com writes "There's an interesting read at National Geographic by Kenneth Brower that probes the case of Tilikum, the homicidal killer whale, who killed his first trainer, 20-year-old Keltie Byrne in 1991. Then in July 6, 1999, a 27-year-old man who stayed after the park closed and evaded security to enter the orca tank was found dead and nude, draped over Tilikum's back with his genitals bitten off. Tilikum's most recent victim was Dawn Brancheau, the SeaWorld trainer he crushed, dismembered, and partially swallowed in 2010. 'Almost all students of orca believe that they are deranged by captivity, some more than others. Tilikum's record puts him at one end of a continuum. There have been dozens of attacks on trainers by an assortment of orcas in the marine parks around the world. [The movie] "Blackfish" shows video from several of these episodes at SeaWorld,' writes Brower. 'What is remarkable about Orcinus orca in marine parks is not these rare episodes. What is remarkable is their monumental forbearance.' For its part SeaWorld is attempting to cast the filmmakers as the true villains, characterizing them as anti-captivity zealots. The company says '"Blackfish" is inaccurate and misleading and, regrettably, exploits a tragedy that remains a source of deep pain for Dawn Brancheau's family, friends and colleagues.'"

A reader notes that scientists at Cambridge University have found four-stranded DNA in human cells for the first time. "If you've ever studied genetics in school or college, you'll know that the structure of DNA is a double helix. You likely know that DNA carries all of our genetic code. While traditionally we think of only double helix DNA, scientists from Cambridge University in England have made an interesting discovery. According to the researchers, a quadruple helix is also present in some cells and is believed to relate to cancer in some ways. According to the researchers, controlling these quadruple helix structures could provide new ways to fight cancer. The scientists believe the quadruple helix may form when the cell has a certain genotype or operates in a certain dysfunctional state. Scientists have been able to produce quadruple helix material in test tubes for years. The material produced is called the G-quadruplex. The G refers to guanine, which is one of the base pairs that hold DNA together. The new research performed at the University is believed to be the first to firmly pinpoint quadruple helix in human cells."

Endeavour will be the second of NASA's space shuttles to leave the Kennedy Space Center. The ship will piggyback on top of a specially modified 747 and head to a Los Angeles museum this week. From the article: "Endeavour's lifespan was relatively short by shuttle standards - 25 missions over 20 years, totaling 299 days in space. But those flights ran the gamut of orbital odysseys, including the sheer moxie of its May 1992 debut when three astronauts made an impromptu and unprecedented spacewalk to rescue a stranded Intelsat communications satellite."

An anonymous reader writes "The inaugural G-Prize contest, conceived and exclusively sponsored by Gen9, was launched to foster creative and innovative approaches for using synthetic DNA libraries to constructively advance industries such as pharmaceuticals, chemicals, biofuels and agriculture. Winners of the inaugural G-Prize will receive a free library of up to 500 GeneBits DNA constructs. Each GeneBits construct is a double-stranded gene fragment from 500 to 1,024 base-pairs in length, with error rates better than 1:2,500."

Hugh Pickens writes writes "Simone Sebastian writes in the Houston Chronicle that the nation's energy transportation network is undergoing a multibillion-dollar overhaul, as oil and natural gas production surges in new regions of the country and energy producers charge into new areas with technology that can reach oil and natural gas trapped in shale and other tight rock formations leaving pools of crude and gas stranded far from the Gulf Coast refineries and petrochemical plants that need them. 'Where it used to be isn't where it is now. Where it needs to go isn't where it used to go,' says Terrance McGill, president of fuel carrier Enbridge Energy. 'You're seeing this fundamental shift of crude oil across the country.' For example Phillips 66 CEO Greg Garland says his company is considering buying 2,000 more rail cars that could carry an additional 150,000 barrels a day from shale regions (PDF) to its refineries across the country because the glut of crude oil pouring out of the newly tapped shale oil plays like North Dakota's Bakken has kept the price of Mid-Continent crude at a record-wide discount of up to $27 per barrel relative to its rival European benchmark Brent crude because there is not enough pipeline capacity to get Bakken crude to Gulf coast refineries. 'That's a pipeline on wheels,' says Garland. 'You'll see us stepping out and doing some more things around infrastructure. Like everyone else, we're doing everything we can to get more barrels in front of those facilities.'"

First time accepted submitter amcenwest writes with news on the fate of the mis-launched Ekspress-AM4. From the article: "A modern, state of the art communications satellite stranded last August in a useless orbit will constitute a double failure if Russian officials de-orbit the spacecraft as planned, according to an expert from the team hoping to salvage the spacecraft. 'A new Express AM4 orbit could provide 14 to 16 hours of daily Internet coverage for the international scientific research bases in Antarctica,' said Readdy." Unfortunately, the satellite is scheduled to begin a deorbiting burn between March 20th and 26th, so it looks unlikely that it can be salvaged at this point.

theodp writes "After a 17-month wait, 20-year-old Dharun Ravi went on trial Friday for using a remote webcam to spy on an encounter between his roommate and another man in their Rutgers dorm room. The roommate, Tyler Clementi, killed himself days later, jumping off the George Washington Bridge and igniting a national conversation on cyberbullying and gay teen suicide. Ravi is charged with multiple counts of bias intimidation as a hate crime, invasion of privacy and hindering apprehension; he faces up to 10 years in prison and deportation. Defense lawyers on Friday argued that Ravi's actions were the mark of an ignorant teenager, not a hateful homophobe. 'He may be stupid at times,' said Ravi's lawyer. 'He's an 18-year-old boy, but he's certainly not a criminal.' The New Yorker recently offered an in-depth look at the case and the questions it raises. BTW, this might be a good time for Microsoft to retire that Hallway commercial ('Jason gets stranded in the hallway when his roommate is 'tutoring' lady friends in their dorm room. Luckily, with Windows 7, his laptop can now work like an HD DVR. So Jason can entertain himself while waiting. And waiting. Aaand waiting some more.')."

caseih writes "Damaging the embedded chip in your passport is now grounds for denying you the ability to travel in at least one airport in the U.S. Though the airport can slide the passport through the little number reader as easily as they can wave it in front of an RFID reader, they chose to deny a young child access to the flight, in essence denying the whole family. The child had accidentally sat on his passport, creasing the cover, and the passport appeared worn. The claim has been made that breaking the chip in the passport shows that you disrespect the privilege of owning a passport, and that the airport was justified in denying this child from using the passport."

An anonymous reader writes "Australia's national airline QANTAS, famous for never having had a fatal crash, has been grounded effective immediately by its management. The grounding is in response to industrial action by union employees and has stranded passengers all over the world, with 108 planes grounded indefinitely. The Australian Government is seeking an urgent industrial relations hearing in a likely bid to suspend the industrial action and halt further damage to the Australian economy."

Hugh Pickens writes "Renee-Nicole Douceur, the winter manager at the Amundsen-Scott research station at the South Pole, was sitting at her desk on August 27 when she suffered a stroke. 'I looked at the screen and was like, "Oh my God, half the screen is missing."' But both the National Science Foundation and contractor Raytheon say it would be too dangerous to send a rescue plane to the South Pole now, since Douceur's condition is not life-threatening. Douceur's niece Sydney Raines has set up a Web site that urges people to call officials at Raytheon and the National Science Foundation. However, temperatures must be higher than -50 degrees F for most planes to land at Amundsen-Scott or the fuel will turn to jelly. While that threshold has been crossed at the South Pole recently, the temperature still regularly dips to 70 degrees below zero. 'It's like no other airfield in the U.S.,' says Ronnie Smith, a former Air Force navigator who has flown there about 300 times. A pilot landing a plane there in winter, when it is dark 24 hours a day, would be flying blind 'because you can't install lights under the ice.' The most famous instance of a person being airlifted from the South Pole for medical reasons was that involving Jerri Nielsen FitzGerald, a doctor who diagnosed and treated her own breast cancer. Using only ice and a local anesthetic, she performed her own biopsy with the help of a resident welder. When she departed on October 16, 1999, it was the earliest in the Antarctic spring that a plane had taken off."

theodp writes "In his new book, Car Guys vs. Bean Counters: The Battle for the Soul of American Business, legendary car-guy Bob Lutz says to get the U.S. economy growing again, we need to fire the MBAs and let engineers run the show. The auto industry, writes TIME's Rana Foroohar, is actually a terrific proxy for a trend toward short-term, myopically balance-sheet-driven management that has infected American business. In the first half of the 20th century, industrial giants like Ford, GE, AT&T and others used new technologies to create the best possible products and services with the idea that if you build it better, the customers will come. But by the late '70s, if-you-can-measure-it-you-can-manage-it MBAs were flourishing, and engineers were relegated to the geek back rooms. 'Shoemakers should be run by shoe guys,' argues Lutz, 'and software firms by software guys.' Learning that China plans to open 40 new graduate schools of business in the next few years, Lutz quipped, 'That's the best news I've heard in years.'"

From reader Peter McDermott comes word of a computer outage with effects to dwarf those of the one that stranded thousands of US Airways passengers last week. This time, it's United Airlines' systems that are out of commission and unable to handle passenger reservations, leaving passengers stranded all over the U.S. According to Peter, experiencing the resultant delays first-hand at Dulles Airport near Washington, D.C., United planes are being sent on — along with their passengers' luggage — to the cities from which they're to leave tomorrow morning, in anticipation of the computer system being fixed in the interim.

mschaffer writes "A computer glitch Friday night snarled the travel plans of US Airways customers, as reports flooded in of flights grounded around the country." As someone stranded for several hours yesterday by this outage, "glitch" seems like quite a euphemism. With outgoing flights blocked, and new ones arriving full of passengers expecting to meet connections, the atmosphere got a little heated. Customers could see nice weather, and planes lined up outside, but "The System Is Down" trumps all. The E concourse at Charlotte (a US Airways hub) was packed full of customers ranging from livid (a handful) to merely angry (most) to calmly resigned — which means those of us with seats, snacks, and books or computers. It was disheartening to see how brittle is the infrastructure the airline employs; with the part of the system visible to airline employees down, customers thought they might get more information, or even rebooking, through the US Airways website. But that was down, too, and all the desk staff could do is shrug.

astroengine writes "One year after NASA's Mars Exploration Rover Spirit stopped communicating with Earth, mission managers have announced that they will give the stranded rover one more month to send a signal before they scale back the search. But things aren't looking good. In the words of JPL-based Mars rover driver Scott Maxwell, 'Spirit was so close to us, just a year ago. Snap your fingers, and she's a hundred million miles distant and we can't even prove she's alive.'"

Brian "Goat Man" Hopper, spent five days stranded on Roe Island, north of Concord in Suisun Bay, because he was too embarrassed to phone for help. Hopper lived off vitamins and native plants while trying to repair his inflatable raft. "I was embarrassed to be stranded on an island," Hopper said. "I thought I could fix my boat and make it to land ... I didn't want to spend the taxpayers' money to have the Coast Guard come rescue some stupid guy." After almost a week he finally gave up and called a cousin for help. No word on what makes Hopper the "Goat Man."

tsu doh nimh writes "Credit card giant VISA International has suspended its business with ePassporte, an Internet payment system widely used to pay adult Webmasters and a raft of other affiliate programs. A number of adult Webmaster forums are up in arms over the move because many of their funds are now stranded. Visa has been silent on the issue so far, but KrebsOnSecurity.com points to an e-mail from ePassporte founder Christopher Mallick saying the unexpected move by Visa wouldn't strand customers indefinitely. Mallick co-directed Middle Men, a Paramount film released in August that tells the story of his experience building one of the world's first porn site payment processing firms, as well as the Russian mobsters, porn stars and FBI agents he ran into along the way. Interestingly, the speculation so far is that Visa cut ties with ePassporte due to new anti-money laundering restrictions in the Credit Card Act of 2009, which affects prepaid cards and other payment card instruments that can be reloaded with funds at places other than financial institutions."

A traffic jam on the Beijing-Tibet expressway has now entered its ninth day and has grown to over 62 miles in length. This mother-of-all delays has even spawned its own micro-economy of local merchants selling water and food at inflated prices to stranded drivers. Can you imagine how infuriating it must be to see someone leave their blinker on for 9 days?
